I would start by contacting the profile manager with the data you have on your ancestor. But it is an open profile, and obviously in need of some TLC. Notice in the Bio it says "She was the daughter of William Mullins and Katherine Varner. She passed away in 1864"
I think even without considering DNA evidence, it's pretty certain that James Booker was NOT the "daughter of William Mullins".
But it appears the PM for this profile is an active member, so I'm sure if you send him a "Nice and Courteous" message, he will be happy to work with you to get things straightened out.
From my understanding the DNA connection is solely connected through family connections, so most likely correcting the Father will take care of that as well.
Thank You for Caring!
